Works as expected, fast speed installing and opening games, booting Windows 7, snappier response to other programs. 5 times faster than my 7200 rpm WD black hdd, and it can be seen. Considering buying another to make my laptop faster.

This was my first ever ssd and it's so much faster than Hard Drives. My Computer boots and is ready ten seconds after I press the power button. And its so small and thin that I can fit it in the cable management room behind my motherboard tray.

While Samsung makes some of the best SSD's on the market, some of their products still remain a tad pricey for the performance and per GB cost. I just picked this drive up yesterday and already its made a marked improvement over my 64gb Samsung 830 SSD. I will continue to support Samsung SSD's so long as they continue to be reliable and speedy, but I really wish they would make some things a little more affordable.

I have two of this SSD installed on to my old SATA II Foxconn Destroyer. It fast quiet and doesn't get hot it is nice and cool. It is great for with any operating system or storage. The fastest drive that you can have from a SSD.. It have 256 MB cache does have it own drive controller and the best MLC memory based and xpected lifespan is 60 yrs. Updated firmware is a must from Samsung Magician from this website. Improve speed & data protection. Going from RAID 0 with two 256GB 2.5-inch SSD 840 Pro Series. This drive got great power consumption. Great for laptop and desktop.

This is an excellent SSD drive. It provides excellent performance for the price. It is definitely faster than other SSD models within the same price range. I am working with photos on my laptop and wanted a SSD drive to help with the performance. Now the biggest performance bottleneck is the processor (i5) and the editing software. I am so happy with this drive. It really speeds up my process of transferring the photos from my laptop to my primary computer which is backed up regularly. Incredible speed boost.

Installed 840 Pro 256 in Lenovo X230 laptop running Windows 7 pro and increased boot and application speed significantly. It's been like going to a faster processor or more memory. Has lived up to all expectations thus far.

Upon initial Win 7 install my 4K read/write speeds were 32/81MBs respectively. After just 4 days this dropped to 21/42MBs. The machine lags, program open slower, freezes and generally lackluster performance.

This is a very fast unit that works well. For a top end unit it would have been nice to have some more installation hardware provided. I tried to set this up with AHCI...changed the BIOS and Windows registry, but it still will not go into AHCI mode...it m

This drive was bought for use as the boot drive for a desktop I built. With this drive, an ASRock Extreme6 motherboard, and Windows 8, I get 8 second boot times. Yes, that's right. Eight seconds flat. Programs open lightning fast, as do games. I really ha

This is an excellent product. I come from a sandisk extreme 120gb (which by itself is excellent too) and i decided to increase the capacity of my drive because i was almost full on that one. This ssd comes highly recommended by all the hardware sites i re

I love this drive! It is so quick it's crazy. I put this drive in my laptop and it sped it up plus it extended the battery life. I have nothing bad to offer on this product. If you're thinking about getting it, do it!

Before buying, I was on a mission to get my hands on a top quality SSD. I looked up many reviews for SSD's including this ones predecessor, the Samsung 830. That drive was well known to be the best all around in terms of price vs performance. Mac users of

Did a clean Windows7 Install in 10-15 minutes. Boots in 15 seconds from on button to windows use. Windows experience went from 5.9 to 7.7 for disk performance on an old sata II PC. Quiet, no chattering disk noise.

I have installed it with an asus p8z77-v pro. And a new windows 8 pro 64bits. I choose it to have a fast hard drive for my PC game. And it's really fast when I launch FSX or another more recent game. Like F1 2012, Max Payne 3,... Hope it will work long ti

the 840 pro is the fastest and most efficient SSD in existence as of this writing. every review out there will back up this statement. even coming from another SSD (Crucial M4), i noticed faster performance in real-world usage. and i can only assume it wi

The 256GB version performs with remarkable speed and stability. After almost 2 weeks of very heavy use on a fresh install of Windows 8, I've experienced no issues. Samsung's 4th-generation 3-Core MDX Controller has been and still is at the top of the heap

Noticeably quicker than my not so old OCZ Agility. Utility software for tuning works ok. Did not use the cloning software as I've been using TerabyteUnlimited imaging software for years. One thing did amaze me: The Terabyte software doesn't run in windows

This is my first Samsung product, really happy with it overall. Of course reviews have already praised it, benchmarked/demonstrated it's speed, It's lived up to what I've seen thus far. Hard to think of ever going back to platter drives. Years ago, (back
